In this activity, your students will create an interactive foldable that includes a proof of the Triangle Angle Sum Theorem. This was designed for students to glue into their interactive notebooks. This content falls within both 7th and 8th grade

This document provides a foldable for students to glue into their notes that helps them recognize how to find the interior angle sum of any polygon by splitting it into triangles. This hits 7th and 8th grade geometry common core math standards.

This is a foldable (or flappable if you prefer) designed to help students make a generalization about what conditions must be true to build a triangle. This supports the common core math standard 7.G.A.2. This goes along great with any activity

This worksheet is a great math puzzle for students in 8th-12th grade who need to practice or a challenge finding missing angles. Students will solve the the angle puzzle using angle pair relationships, then their answers will determine what colors
